Didn't find my owls at Blake, as I pretty much suspected. I have the hunch that they disperse pretty widely once the breeding season is over (or for non-nesting birds, once they have determined they will not be nesting this season). They could have been fairly close as the owl flies, but maybe tucked away up some arroyo where they couldn't hear me and I couldn't hear them.
It was a cold blustery day up the Cataract Trail though. Enough so that I was glad to descend and get back to hot food and a shower.
Tonight, I'm heading out again for more hooting.
